摘要(Abstract):

减震沟是降低爆破地震效应的一项重要技术措施。结合工程项目实际,进行减震沟的爆破实验,对有无减震沟的爆破地震波进行了现场测试,对测试数据进行分析计算,研究减震沟对爆破震动作用的一般规律。结果表明,合理利用减震沟可明显降低爆破地震强度,改变地震波频率结构,分散能量,有利于减震。
Damping ditch is an important installation for reduction of blasting vibration effectIn order to investigate the action of damping trench in an actual project,the blasting experiments are carried out and the measurement of seismic wave is made with or without a damping ditchThe measured data are used to study the general rule of the effect of damping ditch on blasting vibrationThe study results show that, when using damping ditch reasonably,the blasting vibration intensity may be distinctly reduced and the spectrum of seismic wave changed,which will decentralize the energy and be favorable to dampen blasting vibration
